This page contains virtual media for the Wang 2200, which presently is
mostly disk images, although in the future tape images may appear.
These files can be used with the emulator, but it is also possible
with enough effort to use the file to create real disk images to get
running again that old Wang computer you found at the curb.

Just about all of the disk images here were contributed. If you have
any old Wang 2200 disks in a box in the back of your closet, please consider
contributing it to help grow this library. I have an 8" floppy connected
to my PC and special hardware and software so I can read these old disks.
In particular, I use a
Catweasel
disk controller and
some custom software
to decode these disks. Note that if you want to do this yourself, you will
need a Catweasel card, and a PC which can run DOS, Windows 95, or Windows 98.
Source code is provided, so it might not be too hard to recompile this to
run on a Linux machine. In theory it should work with a Catweasel Mk 4,
but I have only tried it with the Mk 3 design. The zip file also contains
some notes on how I built an adapter cable to allow connecting the 50 pin
8" drive to the 34-pin connector on the catweasel card.

The "notes" links below mostly just contain the metadata of the disk
and the catalog listing. These were generated by a utility program,
available below. "wvdutil" is written in
Python. Python is a pretty nice
language, and this is my first Python program. Don't expect much.

Version 1.5 of wvdutil
can list the disk catalog, set and clear the disk write protect status, set
and clear program protect mode, list program and structured data files,
check the disk and files for consistency, and change the catalog index style
from the old 2 byte format to the new 2 byte format. See the readme in the
zip for more detailed information. The zip file also contains a windows
executable which can be used if you don't have python installed on your
computer. This executable contains an embedded python interpreter and the
necessary libraries. If you do have python installed on your machine, it
is advisable to use the python version instead of the .exe, as the .exe
is slower to start than the script version.

This disk contains ucode and BASIC-2 diagnostic programs. Although
the programs came on a disk labelled "MVP OS 3.5 disk 2", I don't know
how specific these diagnostics are to that release. In fact, I can
run them under VP OS 2.3, but with one exception.
Under VP OS Release 2.3, BDIAG6 (IF/ELSE tests) fails at line 730.
It is because of this difference in behavior for an odd corner case.

This is a collection of GAMES that were extracted from an old hard drive.
A few are gems; many are rehashes of Creative Computing games.
Some run too fast on a BASIC-2 machine; some depend on the graphics
characters from the 22x6 terminals to be playable.
